Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Please refer to the attached Figure 1-6The utility model provides an embodiment of a width adjustment mechanism for processing a circuit board, comprising an upper width adjustment mechanism 1 and a lower width adjustment mechanism 2, wherein the upper width adjustment mechanism 1 is located directly above the lower width adjustment mechanism 2. A material storage mechanism 3 is provided on the same side of the upper width adjustment mechanism 1 and the lower width adjustment mechanism 2, for storing the circuit board to be processed. The upper width adjustment mechanism 1 is provided with a first drive assembly 101, which is used to drive the adjustment component of the upper width adjustment mechanism through a servo motor, so that the material storage mechanism 3 can be adjusted according to the width requirements of different circuit boards. The lower width adjustment mechanism 2 is provided with a second drive assembly 201, which also drives the adjustment component of the lower width adjustment mechanism through a servo motor. The material storage mechanism 3 includes a material frame top plate and a material frame bottom plate 301, which are connected by a screw mechanism, and the size of the storage space can be flexibly adjusted according to the size of the circuit board. The material frame top plate and the bottom plate are respectively arranged on the adjustment components of the upper width adjustment mechanism 1 and the lower width adjustment mechanism 2. The first drive assembly 101 is matched with the material frame top plate, and the second drive assembly 201 is matched with the material frame bottom plate 301.

[0022] The first drive assembly 101 and the second drive assembly 201 have the same structure and are symmetrical to each other. They are fixedly mounted on the upper width adjustment mechanism 1 and the lower width adjustment mechanism 2. The second drive assembly 201 includes a servo motor 204, an adjustment fork 20101 and a push cylinder 9. A sliding platform 901 is provided on the top of the push cylinder 9 to support and guide the servo motor 204 and the adjustment fork 20101 connected thereto to move forward and backward. Guide rails and balls are also provided on the sliding platform 901 to ensure stability and smoothness during the sliding process.

[0023] The first locking assembly 202 and the second locking assembly 203 are respectively provided on both sides of the second driving assembly 201, which are used to ensure that the position of the storage mechanism 3 is fixed during the width adjustment process. A material frame side plate 302 is provided on one side of the material frame bottom plate 301, and two recesses matching the first locking assembly 202 and the second locking assembly 203 are provided on the material frame side plate 302. These recesses are precisely aligned with the positions of the locking assemblies to ensure that the locking assemblies can be firmly embedded therein during the width adjustment process to achieve a firm locking effect. The first locking assembly 202 and the second locking assembly 203 are controlled by cylinders and can be automatically locked after the adjustment is completed to prevent the storage mechanism 3 from any movement or deviation during the width adjustment process. The locking system designed in this way not only improves the operational stability and safety of the width adjustment mechanism, but also simplifies the operating process and improves the overall production efficiency.

[0024] The material frame bottom plate 301 and the material frame top plate are both provided with the same screw rod 4. The first limit assembly 5 and the second limit assembly 6 are provided on the side of the screw rod 4 close to the upper width adjustment mechanism 1 and the lower width adjustment mechanism 2. A driving fork 8 is provided at the end of the screw rod 4, and the driving fork 8 is matched with the adjusting fork 20101.

[0025] The material frame bottom plate 301 and the material frame top plate are both provided with the same screw rod 4, and the two screw rods 4 are connected by a synchronous belt to ensure synchronization and accuracy during the adjustment process. The end of the screw rod 4 is provided with a driving fork 8, which is matched with the adjustment fork 20101. The rotation of the screw rod 4 is realized by the movement of the driving fork 8, and the top of the push cylinder 9 is provided with a sliding platform 901, which is used to support and guide the servo motor 204 and the adjustment fork 20101 connected thereto to move forward and backward, thereby realizing the contact and separation of the driving fork 8 and the adjustment fork 20101. The adjustment fork 20101 is connected to the servo motor 204. Through the precise control of the servo motor 204, the driving fork 8 can stably drive the screw rod 4, thereby realizing the precise adjustment of the material frame width. This design ensures that during the circuit board processing process, the material frame can be flexibly adjusted according to different circuit board sizes, maintain a stable processing environment, and improve processing efficiency and accuracy.

[0026] The first limiting component 5 is provided with a first limiting rack 501, and the second limiting component 6 is provided with a second limiting rack 601. The first limiting rack 501 is opposite to the second limiting rack 601, and the first limiting rack 501 and the second limiting rack 601 are both engaged with the limiting gear 7. The first limiting component 5 and the second limiting component 6 are equipped with springs, and the top ends of the first limiting component 5 and the second limiting component 6 are set to be pointed shapes.

[0027] The first limit assembly 5 is provided with a first limit rack 501, and the second limit assembly 6 is provided with a second limit rack 601. The first limit rack 501 is opposite to the second limit rack 601, and the first limit rack 501 and the second limit rack 601 are both meshed with the limit gear 7 to achieve the limit control of the screw rod 4. The first limit assembly 5 and the second limit assembly 6 are built with springs to ensure that the limit rack keeps meshing with the limit gear 7 when the driving fork 8 and the adjustment fork 20101 are in a separated state to achieve the locking function. The top ends of the first limit assembly 5 and the second limit assembly 6 are set to a sharp angle shape.

[0028] The first opening plate 20102 and the second opening plate 20103 are respectively provided at both ends of the adjustment fork 20101, and are used to open the first limiting rack 501 and the second limiting rack 601 on both sides of the limiting gear 7 during the adjustment process. The front end of the first opening plate 20102 is provided with a first guide wheel 20104, and the front end of the second opening plate 20103 is provided with a second guide wheel 20105. The first guide wheel 20104 and the second guide wheel 20105 are tangent to the sharp corners of the first limiting assembly 5 and the second limiting assembly 6, respectively, and the first limiting rack 501 and the second limiting rack 601 are smoothly moved through the rolling contact of the guide wheels to unlock the limiting gear 7. This design can not only effectively reduce the friction resistance during the adjustment process, but also improve the accuracy and smoothness of the adjustment.

[0029] In the specific use process, when the width of the circuit board needs to be adjusted, the operator can input the required width value through the control panel, and the first drive component 101 and the second drive component 201 can realize the function of unlocking the limit gear 7 when they are close to the first limit component 5 and the second limit component 6, and use the adjustment fork to drive the driving fork, and use the screw rod 4 to adjust the width of the board storage rack of the storage mechanism 3. When the adjustment is completed, the first drive component 101 and the second drive component 201 are separated from the first limit component 5 and the second limit component 6, and the first limit rack 501 and the second limit rack 601 re-lock the limit gear 7 with the spring elasticity in the first limit component 5 and the second limit component 6 to maintain the width of the board storage rack of the storage mechanism 3. The design of the width adjustment mechanism improves the flexibility and efficiency of circuit board processing, adapts to the processing requirements of circuit boards of different sizes, reduces the time of replacement and adjustment, and improves production efficiency. At the same time, the precise control and stable support of the width adjustment mechanism also ensure the processing quality and avoid processing errors caused by instability.
